{"apiVersion":"1.0","identifier":"CVE-2026-72350","description":"In the Linux kernel, the following vulnerability has been resolved: netfilter: xt_u32: reject invalid shift counts u32_match_it() executes rule-supplied shift operands on a 32-bit value. A malformed u32 rule can provide a shift count of 32 or more, triggering an undefined shift out-of-bounds during packet evaluation. Validate XT_U32_LEFTSH and XT_U32_RIGHTSH operands in u32_mt_checkentry() and reject malformed rules before they reach the packet path.","publishedAt":"2026-08-15T06:22:08","lastModifiedAt":"2026-08-17T06:18:39","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72350","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00176,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72350","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72350","en":"https://www.redsauce.net/en/cves/CVE-2026-72350","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72350","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72350","de":"https://www.redsauce.net/de/cves/CVE-2026-72350","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72350","el":"https://www.redsauce.net/el/cves/CVE-2026-72350"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72350"}}
